高山 マリア

Maria is the supervising teacher of the Neighbors Club. While a child genius, she is also very rude and immature, and often uses a variety of expletives when annoyed. She is also gullible. The reason why Maria cannot make friends is that she is an immature child prodigy whose wisdom stems not as much from natural talent, as from an advanced education. She has an older sister called Kate who is also a nun. [From Wikipedia.org]
